Contrary to popular beliefs, RO purification is a straightforward system. The method is influenced by the natural reverse osmosis process, which the human kidney uses to draw water from the blood.

Apart from the membrane, most standard RO purifiers consist of additional filtering stages. These include mineral and carbon filters.

Whatever gets left behind in the water, post-membrane gets filtered out through the additional filters. Moreover, the activated carbon filter adds the final polish to the output. It removes any foul taste or odor by adjusting the TDS levels.

On the other hand, mineral cartridges add back lost nutrients.

The output of which is better-tasting, healthier water. In the final stage, this water is sent to a storage tank that holds it until the consumer wants to use it.

Despite having different qualities, most RO purifiers look identical. The components are also standard and work in similar ways.

You need to have some basic understanding of these components to assemble RO water purifier your own.

So, let’s have a look at the parts of typical RO purifier:

The inlet valve is the source of water for the RO system. Normally, the valve is set up on the cold water line.

Most of the ROs have a pre-filter as a guard to protect the membrane against salt, silt, and chlorine. It is typically either sediment or carbon filter.

RO membrane is the most significant component that removes considerable health hazards.

Before reaching the faucet, the purified water goes through a post-filter. It is also known as a polish filter. This filter eliminates odor and bad taste, with the by-product tasting sweeter and fresher.

The purified water is then held in this pressurized tank until the consumer opens the faucet.

A restricting valve is used to prevent a backflow of the treated water from the storage tank. The reverse flow could damage the membrane by rupturing it.

The Drain line is mainly attached to the output end of the RO membrane. It discharges wastewater containing contaminants and impurities.

It is a controllable tap to direct water flow and is typically installed on the kitchen sink.

The full form of RO water is Reverse Osmosis Water. RO stands for Reverse Osmosis. This means these kinds of water purifiers employ reverse osmosis technology for purification of water.

Reverse Osmosis (RO) is a unique technology that continually purifies tap water. Toxic chemicals, harmful metals, and illness-causing germs pollute most water sources. Long-term consumption of polluted water can result in severe damage.
